This article will describe how to assess interrater reliability
and validity of risk assessment tools
, using easy-to-follow formulas, and to provide calculations that demonstrate principles discussed.
Clinical nurse specialists should be able to identify risk assessment tools
that provide high-quality interrater reliability
and the highest validity for predicting true events of importance to clinical settings. Making best practice recommendations for assessment tool use is critical to high-quality patient care and safe practices that impact patient outcomes and nursing resources. Optimal risk assessment tool selection requires knowledge about interrater reliability
and tool validity.
The clinical nurse specialist will understand the reliability and validity issues associated with risk assessment tools
, and be able to evaluate tools using basic calculations.
Conclusion: Risk assessment tools
are developed to objectively predict quality and safety events and ultimately reduce the risk of event occurrence through preventive interventions. To ensure high-quality tool use, clinical nurse specialists must critically assess tool properties. The better the tool's ability to predict adverse events, the more likely that event risk is mediated. Interrater reliability
and validity assessment is relatively an easy skill to master and will result in better decisions when selecting or making recommendations for risk assessment tool use.
